Title: Noise Reduction in CMOS Image Sensors for High Quality Imaging The Autocorrelation Function Filter on Burst Image Sequences
Authors: Kazuhiro Hoshino and Frank Nielsen and Toshihiro Nishimura
Abstract: We propose a new method for image noise detection and reduction in complementary metal oxide semiconductor (CMOS) image sensors inspired from audio noise canceling techniques. Our algorithm is based on computing efficiently the time-dependent pixel autocorrelation function (ACF) from constant time interval acquired sequences of images. We demonstrate the effectiveness of our approach for successfully detecting and reducing white noise. Further, we consider an adaptive filter that exhibits significant computational improvements making it highly practical. Finally, we report on experiments displaying the high quality imaging systems obtained in practice.
Keywords: CMOS image sensor, white noise, autocorrelation function (ACF), noise canceller.
